New RS6 6 speed owner

[boca rat]

Update. Hot start issue done, new tires mounted, new gas tank, fuel pump. Nubcake tune in place, no warning lights, one more logged pass to do, then over to Mase and his AWD dyno.

The vibration issue is the biggest issue now, general vibration between 70 and 80. Pulse Racing (who has the car) also has another RS6 (auto) in there with a similar issue, only worse. Short of just steadily replacing every drive train component, how do you go about diagnosing this?

Thx!

Marc at EFI express can also tune for the 01e. He did my car.

Driveline vibration maybe the front axles if they are FEQ remans or other. I was able to source OES GKNs which helped. Some vibration still present, I suspect my driveshaft may need to be rebalanced.

My hot start issue was resolved with a new HD solenoid. Contact Steve on this.
